At one point or another we’ve all lost track of time (“I thought you said our wedding was going to be on Mountain Standard Time!”), but the Hermes Atmos clock from Jaeger-LeCoultre practically demands you never do that again. Magically powered by an hermetically sealed capsule filled with a mixture of gases, this stunner also features an intensely intricate double layer glass dome created specially by glassblowers Les Cristalleries de Saint-Louis. If all that doesn’t compel you to take time seriously, perhaps the 30,000 euros price tag will.
